LGTM!

Wait a second. There are a few cosmetic issues. It is 'orthOgonal', not 'orthAgonal'. Also, let would be preferable instead of var, although it's not much of an issue in this particular case (probably). Just a heads-up.

Isn't this just return vec2(this.x < 0 ? left : right, this.y < 0 ? up : down) ?

Not quite. It does the orthogonal direction closest to the angle of this, so say if you have vec2(-1, -10) it will return UP not LEFT.

Since it is only 4 candidates, I suspect it can be done with a bunch of conditionals, however, it made more sense to use a loop to me. 🤷 It might be faster to use conditionals, but until this function is used somewhere I really can't say.

So

return Math.abs(this.x) > Math.abs(this.y) ?
this.x < 0 ? left : right :
this.y < 0 ? up : down;

Two conditionals will always be faster than calculating 4 square roots (which weren't really needed, the dot product is enough to compare distances).
